記載のモータブレーキ装置。[Claims for Utility Model Registration] 1. A wedge-shaped space 17 is formed between the casing 1 and a rotor 6 rotatably supported within the casing 1, and an annular wedge member 18 is provided on the outer periphery of the rotor 6. The wedge member 18 is arranged to be movable forward and backward in the wedge-shaped space 17, and when the wedge member 18 is moved into the wedge-shaped space 17, a brake is applied to the rotor 6, and the wedge member 18
In the motor braking device, the brake for the rotor 6 is released when the rotor 6 is moved out of the wedge-shaped space 17, and the casing 1 includes a brake that engages with a part of the wedge member 18 to align the rotor axis of the wedge member 18. A notch 20 is provided in a part of the wedge member 18 so that the inner diameter of the wedge member 18 can be enlarged and reduced. A motor braking device characterized in that an inserting member 33 is provided for inserting into the notch 20 to enlarge the inner diameter of the wedge member 18 when the wedge member 18 is moved in the brake release direction. . 2. The insertion member 33 also serves as the engagement body, and when the insertion member 33 engages with the notch 20 of the wedge member 18 and the wedge member 18 is moved in the brake application direction, the insertion member 33 serves as the engaging body. Claim 1 regulating rotation
Motor brake device as described.
